Just like any purchase you can get the best or just good enough. A lot of companies have good and "the best". It is a price point that people appreciate if they are on a budget. The best finishes are what are called "2K" which include a "hardener". The hardener will cross-link the finish making it tougher for longer wear, and more chemical resistant. These types of finish will eventually get thicker and be unusable after a certain amount of time so there will be more potential "waste" if there it too much mixed up for the job, which is another reason that application is more expensive.I for one will only provide the best finish that I am confident with to preserve my work.
